SPECIFICATION forming part of Letters Patent No. 338,286, dated March23, 11386.

Application filed September 23, 1885. Serial No. 177,959. (No model.)

.ToaZZ whont it may concern: 7.

Be it known that I, LUKE A. NIoKEnsoN, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Shears, of whichthe fol lowing is a specification.

-The object of this invention is to furnish tailor-shears, the thumb-bowand lower blade of which have no upward or downward motion while theshears are cutting, having a finger-bow and upper blade that perform allthe upward and downward motion while in the operation of cutting, thatmay be made to I remain in working position, whether in use or not; thathave a lower blade-point so formed that it will pass between a table-topor other plane surface and the edge of the fabric to be out withoutfirst raising the latter, and that are provided with a laterally elasticjoint of novel construction.

This invention consists in producing tailorshears provided with acontinuous upwardcurved lower blade-shank and thumb-bow, the formerprojecting upward sufiiciently to elevate the latter far enough above acutting-table to allow the fingerbow to perform all the cutting motion.

This invention consists, further, in furnishing the thumb-bow oftailor-shears with a downwardprojecting rest, wheeled or not, aspreferred, and in beveling the upper portion of the free end of theirlower blade to a blunt edge, both shear-blades being secured together bya joint-bolt passed through a rubber washer and other attachments toproduce a laterally- I elastic joint.

Referring to the accompanying drawings, which form a part of thisspecification, Figure 1 represents a view of a pair of tailor-shearsembodying my invention. Fig. 2 represents a plan view of a part of thewheeled rest. Fig. 3 represents a view of a modification of the rest.Fig. at represents a View of a transverse section of Fig. 1, through theline :0. Fig. 5 represents a view of the free ends of the shearbladesclosed.

Similar letters refer to similar parts throughout the several views.

A represents the upper surface of a cutting table.

B B 13 represent, respectively, the upper blade, finger-bow, andbladeshanlr of a pair of shears.

B represents a circular perforation through the blade B.

B" represents a circular countersink in the blade B.

O G 0 represent, respectively, the lower blade, thumb-bow, andblade-shank of a pair of shears, the lower surface of the blade C beinga plane.

0 represents a circular perforation through the blade 0, provided withan internal screw.

0* represents a beveled point of the shearblade 0, the beveled point 0serving to raise the edge of any fabric to be cut from the uppersurface, A, of a table.

D represents a rest-shank secured to or continuous with the thumb-bow C.

D represents a short axle. D represents small wheels, having circularperforations at D D represents screws serving as journals for the wheelsD", and also securing them to their axle D.

D represents a screw forming a swivel-joint between the rest-shank D andaxle Da modification of the foregoing.

E represents a joint-bolt having a milled edge, and provided with anexternal screw, E

E E" represent, respectively, a brass and a rubber washer, both circularin form.

F represents a circular set-nut, having a milled edge and circularperforation, the latter provided with an internal screw.

The line 0; indicatesthe plane of the section shown in Fig. 2.

The broken lines 3 indicate the position of the upper blade when theshears are closed.

I claim as new- 1. The combination, with the blade B, provided with thecountersink B, the finger-bow B, and the shank 13*, of the blade 0,having its lower surface a plane and the free end thereof beveled to ablunt edge, and having the thumb-bow C and downward-projecting rest,consisting of the parts D, D, and D substantially as described.

2. The combination, with the joint-bolt E, having the head E andexternal screw, E, of the brass washer E", rubber washer E, and set- ICOnut F, provided with an internal screw, substantially as set forth.

3. The combination, with the rest-shank D, of the axle D, wheels Dscrews D, and swivel- 5 joint screw D substantially as set forth.

4. Tailor-shears provided with a wheeled rest projecting downward from athumb-bow, having their lower blade beveled to a blunt edge at the upperportion of its point, and furnished with a non-rotatingjoint-b01t,whereon IO their upper blade moves when in the operation ofcutting, substantially as and for the purpose specified.
